Investigation of sorption phenomena by solid-phase extraction and liquid chromatography for determination of some ether derivatives of tetrabromobisphenol A

• Observed sorption and chromatographic behaviour served as a starting point for examination of four ether derivatives of the flame retardant tetrabromobisphenol (TBBPA). To date, there is little or no information about these compounds in the scientific literature. The targets in the present study had calculated log Kow values of 6.0–10, indicating a rather hydrophobic nature. A broad range of different types of solvents were used in order to elucidate the mechanisms of sorption on one hydrophilic surface (silica) and two hydrophobic surfaces (polystyrene divinylbenzene polymers). Also, three chromatographic columns (C18, C8, and dual C18-based) were evaluated. In general, the most hydrophilic and the most hydrophobic derivatives (dihydroxyethyl- and di(2,3-bromopropyl), respectively) were more easily desorbed from the studied surfaces by the selected solvents.Regardless of the experimental test conditions applied, the lowest recovery was seen for dimethoxy-TBBPA, followed by TBBPA itself. Also, this study claims that the polar character of the dual-phase column was not as pronounced as asserted by the manufacturer.
